[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a three-dimensional model processing apparatus and a three-dimensional model processing method according to the present invention will be described with reference to the drawings. As an embodiment of the present invention, a three-dimensional modeling system to which the configuration of the present invention is applied will be described. The present system is a system that executes various processes such as deforming or coloring an object composed of three-dimensional polygons by a method imitating the deformation of clay.

First, the outline of the processing executed by the system will be described with reference to FIGS. FIG. 1 (a)
Is an example of an initial screen displayed on the display of the present system. On the display screen 101 of the display, a three-dimensional (3D) object 102 (here, a planar object is used as an example for simplicity) and a cursor 103 are displayed. A menu 104 is displayed on the right side of the screen. The menu 104 has two group boxes: a cursor mode setting box and a tool type setting box.

The user selects a function of the cursor using the cursor mode setting box. For example, when the cursor tool setting mode is set, the cursor 103 becomes 3
The D object 102 has a function of setting the type of tool. That is, in the three-dimensional model processing device of the present invention,
Instead of setting a tool type for a cursor which is a tool for performing various processes, a tool type is set for an object itself to be processed. The user can set an arbitrary tool type in an arbitrary area of the 3D object 102. By operating a cursor on the 3D object area in which the tool type is set, processing according to the set tool type is performed by the object. Is executed.

The user can use this tool setting function to
A tool type can be assigned to an arbitrary area of the 3D object 102 in such a manner that a color is painted on the 3D object 102. Hereinafter, for simplicity, the 3D object 102
The type of tool assigned to is called "tool color"
The act of assigning a tool type to an object is called "painting".

When the mode of the cursor 103 is set to "clay deformation" in the cursor mode setting box, the cursor 103 is set to have a function of deforming the 3D object 102. By setting this function, the user can deform the 3D object 102 in such a manner as to deform the clay by processing such as passing the cursor 103 over the surface of the 3D object 102. Hereinafter, this deformation operation is referred to as “clay deformation”. This modification is defined in advance by the set tool type.

FIG. 1B shows a state in which a tool color is applied to the 3D object 102 using a cursor in the tool setting mode. The user traces the 3D object 102 by using the cursor 103 while pressing the button of the pointing device, so that the tool color,
For example, a tool A color or a tool B color can be painted on a desired area of the 3D object 102. In FIG. 1B, the left half of the 3D object 102 is painted with a tool A color, and the right half is painted with a tool B color.

FIG. 2C shows a state after the cursor mode is switched to clay deformation in the cursor mode setting box. In the tool type box, in addition to the tool A and the tool B, a new default item appears. Here, the type of tool is set to tool A or tool B, and the cursor 103 is set to 3D.
When the tool is acted on the object 102, the tool of the tool A or the tool B is set for the cursor 103, and the set tool A or tool B is subjected to clay deformation according to a predetermined deformation mode. On the other hand, when the tool type is set to the default in the tool type box, a deformation corresponding to the tool color painted on the portion of the 3D object 102 on which the cursor 103 operates is executed. That is, the tool A of the 3D object 102
When the cursor 103 acts on the color area, the deformation according to the setting of the tool A occurs, and when the cursor 103 acts on the tool B color area of the 3D object 102, the deformation according to the setting of the tool B occurs.

FIG. 2D shows a 3D image in which the tool A is painted.
This is the result of clay deformation of the area of the object 102.
The clay deformation is executed by pressing the cursor 103 against the 3D object 102 while pressing the button of the pointing device. 3D object 1
02 undergoes clay deformation according to the amount of movement of the cursor 103. The deformation at this time is executed according to the deformation mode set for the tool A.

A description will be given of a modification set for each tool. FIG. 3 shows the transition of the position of the cursor 302 at the time t {k-1, k, k + 1} and the 3D object 3
01 is shown. From time t = k to time t = k +
When transitioning to 1, the cursor 302 is passing through the 3D object 301, and the clay deformation is executed at the timing of passing.

In the example of FIG. 3, the cursor 302 is 3D
In this example, the transformation process is executed on condition that the object has passed the object 301.
However, it is not essential to set to execute the deformation on condition that the object has passed the 3D object 301,
For example, the transformation may be performed on condition that the cursor touches the surface of the object. Further, the configuration may be such that the deformation is executed on condition that the object is approached from a predetermined threshold value.

FIG. 4 shows an example of clay deformation.
FIG. 4 is a diagram in which the object plane is deformed by deforming the space using a function using the distance from the center point through which the cursor passes as a parameter. Deformation in a three-dimensional space defines, for example, a local space that includes a part or the whole of the shape of a 3D object, and deforms the space.
on)). The degree of space deformation by FFD can be changed by the value of the deformation parameter. The height h of the cone system shown in FIG.
1 and the radius d (FallOff radius) of the bottom surface: 402 are used as parameters, and the deformation mode can be changed by changing these parameters. The function representing the deformation of the xyz space can be defined as shown in the following equation using the parameters d and h, for example.

[0033]

(Equation 1)

Using the transformation method defined by the above formula, the transformation of the cursor is made to correspond to the degree of transformation, and the transformation of the 3D object is performed at the timing when the cursor passes through the 3D object. Such deformation as pressing a soft object can be performed.

By setting the parameters d and h to different values in the tool A and the tool B, the tool A
In the object area in which is set and the object area in which the tool B is set, different deformations can be generated even when the cursor is made to act on the object in the same manner.

FIG. 2E shows the result of clay deformation of the area painted with the tool B color. In this example, the difference between the deformation processes performed by the tool A and the tool B is shown in FIG.
The tool A sets the deformation parameter so that the FallOff radius: 402 is smaller than the tool B compared to the difference in the size of the f radius: 402.

When a clay is deformed by operating a cursor on a 3D object on which a tool color has been painted in advance, the system automatically selects the type of tool according to the tool color painted on the 3D object. Differences appear in the results of clay deformation in the area.

Next, an example of a hardware configuration of the three-dimensional model processing apparatus of the present invention will be described. The three-dimensional model processing apparatus of the present invention has hardware as shown in FIG. A control unit, for example, a computer 502 receives data from the pointing device 501, processes the data, and outputs the processed data to the display 503. Display 50
Reference numeral 3 denotes a display unit such as a CRT or an LCD for displaying computer graphics, images, GUIs, and the like rendered by the control unit 502.

The cursor displayed on the display 503 is controlled by the operation of the pointing device 501 by the user. The pointing device 501 is
For example, a device such as a mouse or a tablet having a sensor for utilizing a two-dimensional or three-dimensional position and several buttons. For example, a computer 50 as control means
2 comprises a general personal computer, a game machine, or the like. Control means (computer) 502
Has a detachable storage device capable of inputting and outputting data such as software, and a network device for communicating with a network such as the Internet.

FIG. 6 is a functional block diagram showing a detailed configuration of functions of the control means shown in FIG. 5, for example, the computer 502. In a tool setting unit 601, a 3D object unit 602, and a processing execution unit (clay deforming unit) 603 shown in FIG. 6, a menu unit 604 can be configured to be controlled by software. It is composed of a memory such as a RAM and a ROM which can be used as a CPU, a CPU for executing arithmetic processing, and other storage means such as a hard disk.

The tool setting unit 601 executes control for painting the 3D object controlled by the 3D object unit 602 with a tool color such as the tool A color or the tool B color. When the mode of the cursor set in the menu 104 is the tool setting mode, the tool setting unit 601 inputs data from the pointing device 501 and controls the cursor 103 (see FIGS. 1 and 2). In addition, the cursor 103 is rendered and displayed on the display 503.

The 3D object unit 602 stores the 3D object 102 such as the shape and color of the 3D object 102.
It has various attribute data. The tool setting unit 601
The D object 102 is rendered and displayed on the display 503.

The processing execution unit (clay deformation unit) 603 is a 3D
The processing control of the clay deformation of the object 102 is executed.
The processing execution unit (clay deformation unit) 603 inputs data from the pointing device 501 and controls the cursor 103 when the cursor mode in the menu 104 is the clay deformation mode. In addition, the cursor 103 is rendered and displayed on the display 503.

In this embodiment, the processing execution unit (clay deforming unit) 603 is described as performing deformation processing on an object. However, the three-dimensional model processing apparatus of the present invention not only deforms the shape of the object but also deforms the object. For example, it is also applicable to coloring, color changing processing, and the like. These will be described later.

The menu section 604 displays and controls a menu 104 which is a graphical user interface for setting a cursor mode and a type of tool. Tool setting unit 601 according to an input from the user
And a processing execution unit (clay deformation unit) 603 are controlled.

[Tool Setting Processing] Next, details of the tool setting section 601 will be described with reference to the block diagram of FIG. Further, the operation procedure will be described with reference to FIG. As shown in FIG. 7, the tool setting unit 601 includes a cursor control unit 701, a vertex selection unit 702, and a tool update unit 703.

According to the flow of FIG. 9, the tool setting section 60
Process 1 will be described. When the tool setting unit 601 detects a change in the state of the pointing device 501 during the standby state (S901) (S902), the cursor control unit 70
1 inputs the position data from the pointing device 501 and moves the cursor 103 (see FIGS. 1 and 2) (S903). In addition, the cursor 103 is rendered and displayed on the display 503. The detection of a change in the state of the pointing device 501 in step S902 is event detection processing such as movement of the pointing device, pressing of a button of the pointing device, or the like, and is processing for detecting that some operation has been performed on the pointing device.

Next, the vertex selection unit 702 inputs the coordinates of the cursor 103 from the cursor control unit 701, and searches for the vertex coordinates of the 3D object 102 near the coordinates. Cursor 103 and 3D object 10
When the cursor 2 and the cursor 103 are sufficiently close to each other, the distance between a part of the vertices of the 3D object 102 and the center of the cursor becomes equal to or smaller than a certain value, and the vertices of the cursor 103 are included in the area of the cursor 103. It is determined whether there is a vertex included in the area of the cursor 103 or not (S
904). 3D object 10 near the cursor 103
If there are vertices of 2, these vertices are acquired and input to the tool update unit 703 (S 905). If not, it enters a standby state (S901).

In the tool update unit 703, the menu 104
Enter the type of tool from 3D object 1
02 is set as an attribute value to the vertex coordinates constituting S2 (S9
06). As a specific process, the vertex is painted with the tool color. Thereafter, the process enters a standby state (511). The tool color is set in advance for each type of tool, and the 3D object 1 included in the area of the cursor 103 when the cursor 103 approaches the 3D object 102
The attribute of vertex 02 is set to the tool color.

[Clay Deformation Processing] Next, the processing execution unit (clay deformation unit) 603 will be described in detail with reference to the block diagram of FIG. Further, the operation procedure will be described with reference to FIG. As shown in FIG. 8, the processing execution unit (clay deformation unit) 60
Reference numeral 3 denotes an intersection detection unit 801, a cursor unit 802, an FFD transformation unit 803, an FFD generation unit 804, and a tool selection unit 805.
Having.

The processing performed by the processing execution unit (clay deforming unit) 603 will be described in detail with reference to the flow of FIG. When the process execution unit (clay deforming unit) 603 detects a change in the state of the pointing device 301 during the standby state (S901) (S1002), the cursor unit 802 inputs data from the pointing device 301 and inputs the data from the cursor 103.
Is moved (S1003). In addition, the cursor 103 is rendered and displayed on the display 503.

The intersection detection unit 801 inputs the position data of the movement path 302 (see FIG. 3) of the cursor 103 from the cursor unit 802, and the path data and the 3D object 102 are input.
It is checked whether or not has crossed (S1004). If no intersection is detected, the process enters a standby state (S901).

When the intersection of the moving path 302 of the cursor 103 and the 3D object 102 is detected, the tool selecting unit 805 finds the intersection of the moving path of the cursor 103 and the 3D object 102, and determines the 3D object closest to the intersection. The vertices constituting the object 102 are searched for, the type of tool set for the vertex is read, and the type of tool to be used is determined (S1005). If a specific tool is set as a tool type other than the default on the menu 104, the tool type is followed.

Next, the FFD generation unit 804 sets the cursor 1
An FFD block is generated from the moving route 03 and the type of tool (S1006). This FFD block is defined by, for example, a function that executes the transformation described above with reference to FIG. The function is a function as shown in the above [Equation 1].

Next, the FFD transformation unit 803 transforms the 3D object 102 using the generated FFD block (S1007). That is, the 3D object 10
2 is transformed into clay. A general FFD will be briefly described. This method does not directly deform the object itself when deforming the three-dimensional object, but first sets a local space where the object exists, and deforms the local space. Then, the object is deformed according to the distortion of the space. In addition, FFD is Alan

The present invention has a feature that various kinds of tools can be set in an arbitrary area of the 3D object itself. Normally, the vertices of the 3D object have attributes such as coordinate values, colors, and materials possessed by the vertices. In the present invention, the type of the tool is further provided as an attribute.

A specific example of a method of assigning a tool type as an attribute to a vertex of a 3D object will be described with reference to FIG. FIG. 11 shows a plane formed by a plurality of polygons. The plane is defined as a plane constituting the 3D object. The vertices forming the polygon are v1 to v9. A tool type is assigned to each of the vertices v1 to v9 as an attribute. For example, the i-th vertex vi is
It has attributes such as i = (pi, ci, mi, bi). Here, pi represents the position of the vertex, ci represents the color of the vertex, mi represents the material of the vertex, and bi represents the type of tool assigned to the vertex. 3D object part 6 described above with reference to FIG.
02 displays the 3D object on the display according to these attributes.

The three-dimensional model processing apparatus of the present invention determines the type of tool used when deforming a 3D object from the attribute of the type of tool set at the vertex of the 3D object as described above. The determination of the tool type depends on the movement path of the cursor and the 3
The intersection of the D object is detected, and is executed based on the tool type attribute set at the vertex closest to the intersection.

A description will be given of a specific processing example for acquiring the attribute set at the constituent vertices of the polygon shown in FIG. 11 based on the detection of the intersection of the moving path of the cursor and the 3D object. A vector indicating the intersection between the cursor movement path and the 3D object is defined as [vector P], and the vertex of the object closest to this [vector P] is detected. The vertex closest to the intersection can be obtained by the following equation.

[0060]

(Equation 2)

In the above equation, [vector Vi] is i
A vector indicating the position of the vertex. The above equation finds i at which the norm value of the above equation becomes the minimum value for all possible values of the parameter i. The i-th vertex having the minimum value selected in this way is selected as a vertex that is close to the intersection of the cursor movement path and the 3D object, and the type of tool set as an attribute to the selected vertex is the cursor. 103 is a 3D object 10
2 is recognized as a tool when applied to the 3D object 102, and a deformation according to a preset deformation mode is performed on the recognized tool. The deformation mode set in the tool is, for example, as shown in FIG.
2D. For example, the parameters d and h of Equation 1 are set to different values for each tool, and the 3D object area where different tool settings are made as shown in FIG. Then, a deformation process in a different deformation mode is executed.

In the above description, the tool type is 2
Although the deformation processing using one tool A and tool B has been described, the number of types of tools may be set to a large number of three or more, and different deformation modes may be set respectively.
Of course it is possible. Furthermore, in addition to the deformation processing, paint and coloring tools such as brushes and sprays are set, and coloring modes according to various tools such as brush A, brush B, spray A and spray B are set for each tool. By setting the type of tool as an attribute value in an arbitrary area of the 3D object, the user can apply a cursor to the 3D object whose tool type is set as an attribute without switching the tool, and thereby set the tool type. Various processings can be performed according to.

In the above description, an example in which a different tool is set for each partial area for one object has been described. For example, a plurality of objects are displayed on a display, and the type of tool is set for each object. Can also be set.

FIG. 12 shows a specific application example. A plurality of objects 1201 to 1204 as shown in FIG.
Is displayed on the display, and a deformation process of each object is performed by the cursor 1200. Here, the objects 1201 to 1203 are objects supposed to be potted plants, and a predetermined deformation tool is set as an attribute of the vertices constituting the objects 1201 to 1203.
That is, as shown in FIG.
Set only for 3.

The user positions the cursor 1200 on the surface of the objects 1201 to 1203, so that the deformation set as the attribute of the vertices of the objects 1201 to 1203, that is, a flower-like deformation as shown in FIG. The transformation 1205 is performed automatically. Since the same tool type attribute as that of the objects 1201 to 1203 is not set in the object 1204, the flower does not bloom even if the user touches the cursor 1200 with the object 1204.

The present invention has been described in detail with reference to the specific embodiments. However, it is obvious that those skilled in the art can modify or substitute the embodiment without departing from the spirit of the present invention. That is, the present invention has been disclosed by way of example, and should not be construed as limiting. In order to determine the gist of the present invention, the claims described at the beginning should be considered.

[0067]

As described above, according to the three-dimensional model processing apparatus and the three-dimensional model processing method of the present invention, when executing various processes such as deformation and coloring of an object, switching of tools is performed. , Different processes for each object or each partial region of the object, for example, processes according to different deformation modes are automatically executed according to the tool attribute set in an arbitrary region of the object. Therefore, the user can significantly reduce the number of complicated tool selection operations, and can concentrate on the 3D object deformation operation.
